Used extensively in glass manufacturing due to its high melting point and purity, providing the primary silica source for container, flat, and specialty glass. Plays a critical role in foundry operations as a molding material for metal casting, offering thermal stability and dimensional accuracy. Serves as a proppant in hydraulic fracturing to keep fractures open in oil and gas wells. Employed in water filtration systems for its effective particulate removal properties. Utilized in construction as a key component in concrete, mortars, and cement mixtures to enhance strength and durability. Also used in the production of silicon metal and silicon-based chemicals through high-temperature reduction processes.
